Comment 7 for bug 222220

This bug is easy to fix.

- First edit your Locales File: sudo nano /usr/share/i18n/locales/es_XX
 XX is for your counrty code (VE, AR, ES, etc...)

Find the flollowing lines:

am_pm "";""
t_fmt_ampm ""

- And replace them with this one:

am_pm "<U0041><U004D>";"<U0050><U004D>"
t_fmt_ampm "<U0025><U0049><U003A><U0025><U004D><U003A><U0025><U0053>/
<U0020><U0025><U0070>"

- Save changes.

- Then type the following command to complete changes: sudo locale-gen

- And restart your system, when you login again 12 hrs format will be working.

Best Regards.
